“The book casts a fresh light on the relationship between ultra vires conduct of public bodies and the reason underlying rights to restitution in such circumstances. It is a well-written and valuable contribution to both restitution and public law scholarship. This work is likely to be very valuable not only to academics but also to practitioners (tax and non-tax) advising on restitution claims involving national or EU public bodies.” – Rafal Zakrzewski,
British Tax Review, No. 3
“Williams...presents a clear and well-argued case for a public law of unjust enrichment. Her approach is thoughtful and considered covering key cases in English, French and EU law, and focuses on an area of law of particular topicality....While her argument does, as she states, remain normative, lacking case law support, she nevertheless provides a lucid and well-researched argument for reform. Williams must thus be praised for drawing together and critically appraising the leading cases in this field and for providing valuable insight into this developing area of the law.” – Paula Giliker,

“Unjust Enrichment and Public Law is an important contribution to this topical subject.
The discussion of English law is comprehensive and well argued, and will interest both public and private lawyers.
Unjust Enrichment and Public Law is a well-written and well-presented book, which does much to advance our understanding of this difficult area of law. It deserves the attention of lawyers across the public/private divide.” – Paul S. Davies,
The Law Quarterly Review, Volume 127
